I can confirm that the latest (free) version of Ccleaner v5.42 wiped out my Chrome (latest) settings. Has not happened ever before, only with the latest release 5.42. Happened on two of my machines, both running Win7 (with all the latest updates), one is 64-bit, the other 32-bit. Ccleaner v5.42 has a nasty bug about the Chrome settings. Please overview and correct the issue. Thanks PS: just overinstalled v5.41 over the v5.42 and the issue is not there with 5.41.
